      <p>A new method has been added to the Berkeley DB environment handle,
<a href="../api_reference/C/envset_flags.html" class="olink">DB_ENV-&gt;set_flags()</a>.  This method currently takes three flags:
<a href="../api_reference/C/envset_flags.html#set_flags_DB_CDB_ALLDB" class="olink">DB_CDB_ALLDB</a>, <a href="../api_reference/C/dbopen.html#open_DB_NOMMAP" class="olink">DB_NOMMAP</a>, and <a href="../api_reference/C/envset_flags.html#envset_flags_DB_TXN_NOSYNC" class="olink">DB_TXN_NOSYNC</a>.  The
first of these flags, <a href="../api_reference/C/envset_flags.html#set_flags_DB_CDB_ALLDB" class="olink">DB_CDB_ALLDB</a>, provides new functionality,
allowing Berkeley DB Concurrent Data Store applications to do locking across multiple databases.</p>
      <p>The other two flags, <a href="../api_reference/C/dbopen.html#open_DB_NOMMAP" class="olink">DB_NOMMAP</a> and <a href="../api_reference/C/envset_flags.html#envset_flags_DB_TXN_NOSYNC" class="olink">DB_TXN_NOSYNC</a>, were
specified to the <a href="../api_reference/C/envopen.html" class="olink">DB_ENV-&gt;open()</a> method in previous releases.  In
the 3.2 release, they have been moved to the <a href="../api_reference/C/envset_flags.html" class="olink">DB_ENV-&gt;set_flags()</a> method
because this allows the database environment's value to be toggled
during the life of the application as well as because it is a more
appropriate place for them.  Applications specifying either the
<a href="../api_reference/C/dbopen.html#open_DB_NOMMAP" class="olink">DB_NOMMAP</a> or <a href="../api_reference/C/envset_flags.html#envset_flags_DB_TXN_NOSYNC" class="olink">DB_TXN_NOSYNC</a> flags to the
<a href="../api_reference/C/envopen.html" class="olink">DB_ENV-&gt;open()</a> method should replace those flags with calls to the
<a href="../api_reference/C/envset_flags.html" class="olink">DB_ENV-&gt;set_flags()</a> method.</p>
